With normal electricity consumption, the capacity of your meter ( average 9.2 kVA ) should suffice. With this, you can theoretically equip devices with a total capacity of maximum 9.2 kW or 9200 watts simultaneously. Since you never use all your electrical devices at the same time, your basic installation is more than sufficient in practical terms. Dealing with the TXU Energy Reviews comes within the capabilities and there comes the perfection of the entire deals.

If you have special installations that use a lot of energy, such as a sauna, a ceramic oven or an electric car, then that capacity may not be sufficient.

Does this seem complicated? Then ask your electrician for advice

By taking your energy needs into account, he will be able to determine your electrical capacity.

How do I calculate the maximum power of my electrical installation?

  • To calculate the maximum power that your meter can deliver (expressed in volts amperes), multiply the voltage (U) by the intensity (I) of the current that supplies your home.
  • Most homes are equipped with 230 volts (V) single-phase with an intensity of 40 amps (A). The maximum power is therefore: 230 V x 40 A = 9 200 volts ampere (9 200 VA) or 9.2 kVA
  • The formula for calculating the power for a three-phase 230 V or 400 V connection is the same, namely: √ 3 x U x I. If, for example, there is a 25 A circuit breaker, you calculate the maximum power as follows *:
  • 3 x 230 : √3 x 230 V x 25 A = 9947.5 VA
  • 3 x 400 + N (ul conductor): √3 x 400 V x 25 A = 17 300 VA
  • (*) Often, for quick calculations or for convenience, √3 is replaced by the approximate value of 1.73. We also used that number here. Fun fact: the difference between the two outcomes is a factor … 1.73! And that is because the voltage 400 V is also 1.73 greater than 230 V.

How do I know if the electrical power of my meter is sufficient?

If you require more electrical power than your meter can deliver, the power switch will trip to protect your installation. If your circuit breaker switches off regularly, this indicates that your installation has insufficient power.

Which meter power (in kVA) for which intensity (ampere)?

The more voltage and intensity, the greater the power of your meter must be. In the table below you can look up what power you need to provide for the intensity that you need.

How can I increase the electrical power of my installation?

Do you want to increase the electrical power of your installation? Then first ask your electrician for advice. He can give you more information about the solution that is most suitable for your needs. There are 2 options:

  • increase the meter power (if your electrical installation can handle it) and stay single-phase.
  • switch to three-phase current and possibly increase the power.

For these adjustments, you must contact the expert, the distribution network operator for natural gas and electricity in the Capital Region. It is responsible for the electrical connections, independent of the energy suppliers. The installation costs are invoiced to you, but they do not affect your monthly invoice, which is not increased.
